Origin: Formed within English, by compounding; modelled on a French lexical item. Etymons: electro- comb. form, dynamic adj.

Etymology: < electro- comb. form + dynamic adj., after French électro-dynamique (A. Ampère Feb. 1822, in Jrnl. de physique, de chim. et d'hist. naturelle 94 62). Compare slightly earlier electrodynamics n. and electrodynamical adj.

Physics.

1. Of or relating to electrodynamics. Cf. quantum-electrodynamic adj. at quantum n. and adj. Compounds 2.
